Plug-in hardware module for the STM8S-DISCOVERY

interface for DALI communication

■

Level translation from DALI voltage levels (-6.5 
to 22.5 V) to microcontroller levels (3.3 V / 5 V 
logic)

■

Proper rise/fall times for the communication

■

Current consumption limit (2 mA max.)

■

Overvoltage protection for misconnection of 
rated mains voltage to DALI DA connectors

■

RoHS compliant

The STEVAL-ILM001V1 is a plug-in module for 
the STM8S-DISCOVERY kit and SW DALI library, 
to create a fully working DALI slave application. 
The STM8S-DISCOVERY + STEVAL-ILM001V1 
work as a DALI slave device and can be 
connected to and controlled by any DALI network.

The LD1 on the STM8S-DISCOVERY kit is used 
as a light source. Its brightness, fade-in/out times, 
etc., as defined by the DALI standard, can be 
controlled through DALI to simulate a normal 
lamp behavior.

The DALI (Digital Addressable Lighting Interface) 
standard is a communication protocol widely used 
in intelligent lighting applications. Its use is not 
limited to fluorescent tube lamp dimmable 
ballasts, for which it was initially designed, but 
also for future LED applications.

The user is expected to be familiar with the DALI 
standard and its details.
